The solutions in the two arms of a U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 4M sucrose and 2M glucose. Side B is filled with 2M sucrose and 3M glucose. Initially, the solution in side A, with respect to side B is______________.
Answer:
hypertonic
Explanation:
The solution in side A is hypertonic with respect to side B.
A hypertonic solution is a solution with a higher concentration of solutes in comparison with a neighbouring solution separated by a selectively permeable membrane.
In terms of both sucrose and glucose concentrations, the solution in side A is higher than the solution in side B of the U-tube. Hence, side A is hypertonic to side B.
A hypertonic solution is as opposed to a hypotonic solution with the latter having a lower concentration of solutes as compared to a neighbouring solution. Isotonic solutions have equal solute concentrations with their neighbouring solutions.

B. to determine the exact number of offspring having a particular genotype
C. to determine the probability of an offspring having a particular phenotype
D.to determine the probability of an offspring having a particular genotype
The purpose of using a Punnett square in studying genetics is to determine the probability of an offspring having a particular genotype. Thus, the correct option for this question is D.
What is Punnett square?Punnett square may be defined as a type of table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are determined. It is named after Reginald C. Punnett, who proposed this approach in 1905.
In genetics, Punnett square is extremely utilized in order to predict the possible outcomes of two unknown genotypes. With the help of these genotypes, phenotypes of a specific set of alleles are also determined. The important concept of Punnett square is that it always determines the probability, not the exact number.
Therefore, to determine the probability of an offspring having a particular genotype is the purpose of using a Punnett square in studying genetics. Thus, the correct option for this question is D.

Warm the planet
Explanation:
The rapid increase in global CO2 in the 21st century has raised concerns over the lingering effect of global climate change which could result due to the exponential increase in CO2 emission at this time. This rise in global atmospheric CO2 has been observed to have a positive relationship with the level of industrial carbon emission. The rise in emission of industrial carbon has been tipped to be responsible for the exponential rise in global atmospheric CO2. CO2 is a form of green house gas responsible for warming the planet.

A solution that is equal in solute concentration to that of the cytoplasm of a cell and causes a cell to neither lose nor gain water by osmosis is a(n)
Answer:
isotonic solution
Explanation:
The cell membrane is semi-permeable, so it allows to pass through certain solutes. By a process called osmosis, the water molecules move from a compartment of lower concentration of solutes to a compartment with higher concentration.
Therefore, if the concentration of solutes in the outside is higher than the concentration in the cytoplasm (hypertonic solution), the water molecules will move from the interior to the exterior. Conversely, if the cytoplasm is more concentrated than the outside (hypotonic solution), the water molecules will move from the exterior to the interior. If the cytoplasm has the same solute concentration as the outside, the solution of the outside is called isotonic, and no water net flux will be produced.

Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years and is the largest contributor to climate change?
Answer:
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.
Explanation:
Why does it matter?
As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.

A simple test to differentiate between Staphylococcus and Streptococcus is the addition of H2O2 to a colony to see if bubbles form, which are positive for catalase. Which organism would be positive
Answer:
The Correct answer is B, Staphylococcus.
Explanation:
The Catalase test is used to differentiate Staphylococci (Catalase positive) from Streptococci (Catalyst negative). The enzyme catalase is produced by bacteria that respire using oxygen and protects them from the toxic by-products of oxygen metabolism.
Catalase positive bacteria includes strict aerobes as well as facultative anaerobes. Catalase negative bacteria maybe anarobes or facultative anarobes that only ferment and don't respire using oxygen as terminal electron acceptor.
Catalase converts hydrogen peroxide to water and oxygen gas. Though both Staphylococcus and Streptococcus are gram positive bacteria, only Staphylococcus produces catalase enzymes.

A food chain consists of several organisms. Suppose one of the organisms in the chain disappears. What effect can this have on the other organisms in the food chain?
Answer:
All organisms in that food chain would starve until they die unless they could possibly move to a different habitat.
Explanation:
And because of all those organisms not being able to properly feed due to an organism missing in the food chain of that habitat, the population of those animals would decrease as well.
Myoglobin levels are higher in Tibetans and other ethnic groups that live at high altitudes. Explain the benefit of higher myoglobin levels for individuals living at high altitudes.
Answer:
They are able to take up and store more oxygen in their muscles
Explanation:
According to Oxford dictionary, myoglobin is ''a red protein containing haem, which carries and stores oxygen in muscle cells. It is structurally similar to a subunit of haemoglobin.''
The fact that Tibetans have a high level of myoglobin implies that they are able to take up and store more oxygen in their muscles since myoglobin is involved in storage of oxygen in muscle cells. Hence elevated levels of myoglobins enables the muscle cells to work more effectively.

what is the task of vessel cells in xylem
Answer:
Tracheal, vessel or vascular cells have one or more pores in their terminal walls. They reabsorb the common walls. They adopt a vertical position and are linked together forming a continuous tube or glass. They constitute the Xylem of angiosperms, plants that have flowers, and their function is to conduct water and other nutrients.
Explanation:
The vascular elements or vessels are specialized tracheids whose terminal walls are crossed by one or more pores; a vertical series of vascular elements that form a continuous tube is called a vessel. The tracheids are cells that conduct water and salts of the xylem, through which the raw sap circulates. It is typical of gymnosperms. The tracheids are unicellular, very elongated and with numerous simple, areolate pits, through which they intercommunicate.

Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1. Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have holdfasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargassum, have gas-filled structures called floats.
2. Algae and plants are like humans as they need food, nutrients and a good environ- ment to grow and survive. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Algae live in water or damp environments
3. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration
